Tools you buy to create items to sell at your retail store (easel, woodworking table, etc.) must come out of retail funds.Further Explanation:
If you want to sell microscope prints, you have to buy your microscope on the retail lot (from retail funds) to create the prints.
If you just want to level your logic skill, you can use household funds to buy chess table, skill books, etc. to level the skill.
If after a week you are no longer selling microscope prints, you can leave the microscope on the retail lot or put it in household inventory. You can sell the obsolete microscope, but it has to be done on home lot, so that it doesn't increase your retail funds.
If we make copies of things that we want to sell, do the copies need to be made at the store?
No you don't. You can buy the microscope at the store, put it in inventory, go back to homelot and make your microscope prints. Copies doesn't have to be made on retail lot, but the tools that create the items must be purchased on retail lot using retail funds.
